A custom-fabricated golf club device comprising a golf club head with a recessed portion located at the front heel portion of the head and machined therein, the recessed portion comprising a substantially semi-spherical aperture. A hosel assembly has a lower portion, having a substantially semi-spherical aperture that aligns with the aperture of the head recessed portion, the hosel assembly further having a recessed portion at an upper portion thereof. A steel ball is located securely within the aperture of head recessed portion and the aperture of the hosel assembly lower portion, functioning to provide positive location of the club head and hosel assembly. In the preferred mode, a permanent weldment functions to securely affix the lower portion of the hosel assembly to the club head at the heel portion of the club head. The device is utilized in conjunction with golf clubs of both the iron and wedge variety to provide a cost-effective and convenient way to custom-fabricate golf clubs to the unique physical characteristics of individual players. By taking advantage of machining, rather than forging or casting the components, a wide range of lie angles with precise resolution can be achieved. In addition, the manufacturing techniques of the present invention diligently conform to the USGA rule that clubs other than putters shall not be designed to be adjustable except for weight.
